由二氧化碳(CO2)和环氧化物合成环状碳酸酯是CO2利用的有效途径. 尽管各类金属催化剂相继见诸报道, 但依然急需开发一类可回收或再循环的催化剂. 该工作将SBA-15负载的N-杂环卡宾-吡啶钼络合物(Mo@SBA-15)作为一类高效和可循环利用的催化剂应用于CO2和环氧化物合成环状碳酸酯. Mo@SBA-15与四丁基溴化铵(TBAB)组成的双组分催化体系在100 ℃和CO2 (1 MPa)压力下合成环状碳酸酯时, 显示出了较高的催化活性. 此外, Mo@SBA-15重复使用7次未发现明显的活性降低.

Synthesis of cyclic carbonates from carbon dioxide (CO2) and epoxides is an effective pathway for the CO2 utilization. Although various metal catalysts have been reported, it is highly desirable to develop a method for the reuse or recycling of catalysts. Herein, an N-heterocyclic carbene-pyridine molybdenum complex supported over SBA-15 (Mo@SBA- 15) was used as an efficient and recyclable catalyst for converting CO2 and epoxides into cyclic carbonates. Mo@SBA-15 in combination with tetra-butylammonium bromide (TBAB) shows high catalytic activity in the synthesis of cyclic carbonates under 100 ℃ and 1 MPa CO2 pressure. In addition, Mo@SBA-15 was reused seven times without any significant activity loss.
